class Prism::ArrayNode

表示数组字面量。这可以是使用方括号的常规数组，也可以是使用 %（例如 %w 或 %i）的特殊数组。

[1, 2, 3]
^^^^^^^^^

属性

elements [R]

表示数组中零个或多个[非空表达式](github.com/ruby/prism/blob/main/docs/parsing_rules.md#non-void-expression)的列表。

new (source, node_id, location, flags, elements, opening_loc, closing_loc)

源代码

# File lib/prism/node.rb, line 867
def initialize(source, node_id, location, flags, elements, opening_loc, closing_loc)
  @source = source
  @node_id = node_id
  @location = location
  @flags = flags
  @elements = elements
  @opening_loc = opening_loc
  @closing_loc = closing_loc
end

初始化一个新的 ArrayNode 节点。

type ()

源代码

# File lib/prism/node.rb, line 987
def self.type
  :array_node
end

返回此节点类型的符号表示形式。请参阅 'Node::type'。

公共实例方法

=== (other)

源代码

# File lib/prism/node.rb, line 993
def ===(other)
  other.is_a?(ArrayNode) &&
    (flags === other.flags) &&
    (elements.length == other.elements.length) &&
    elements.zip(other.elements).all? { |left, right| left === right } &&
    (opening_loc.nil? == other.opening_loc.nil?) &&
    (closing_loc.nil? == other.closing_loc.nil?)
end

实现节点的 case-equality。这实际上是 ==，但不比较位置的值。仅检查位置是否存在。
